    SAN DIEGO--April 3, 2001--PTSC (Patriot Scientific Corp.)(OTCBB:PTSC) the premier provider of embedded systems components and solutions, announced today that it will be demonstrating its IGNITE I technology through an automotive application.
    Visitors will be shown how use of the technology applied to an auto will alert the driver of a broken taillight, detect an overheated engine and automatically start a cooling fan, among several other features. The demonstration will be in booth no. 537 at the Embedded Systems Conference in San Francisco's Moscone Center. PTSC engineers, salespeople, executives and Sun representatives will be present at the event. The system is capable of almost unlimited possibilities for service and safety such as alerting the driver of low brake linings, tire under-inflation or if the engine is running according to specification before any of these conditions become major problems. The PTSC technology may also be configured for use with a global positioning system or developed to alert the driver of a commercial Semi-Truck being illegally overweight before being cited for it.
    "PTSC was able to develop IGNITE I-based mobile services that will both ensure end-user safety and is convenient to use," said R. G. Blum, CEO of PTSC. "Our automobile demonstration is set up to show visitors the potential of our powerful ROSC processors in any Embedded System Application whether it be in automotive, consumer electronics, wireless applications, service gateway or industrial systems."

PTSC has also developed the "e-gastation" concept enabling customers with transponders or sensors on their cars to drive into a networked service station and refuel and know the safety and mechanical status of the car, without cash or inconvenience through PTSC technology.
    "The ESC demonstration will not only enhance driver safety but will offer new solutions to customer relationship management through databases of customer patterns -- helping enable business success of end-user automotive markets," said Mike Korodi, VP sales and marketing of PTSC. "The Gasoline stations and auto repair shops will save administrative costs through the network and know what the pattern of needs are for the particular automobile and its driver."
